I love historical documents/books.
Yesterday, I bought a historical book at a used book store during lunch. It is titled "Boston Architecture" and was written for disturbution at the 1970 AIA convetion in Boston. It is a great book that talks about Boston and Boston architecture at the time. What I find most fascinating about it is its description of the Back Bay. Apparently it was a gritty urban area at the time. Certainly not now.
Oh...to have been a single college graduate in 1969.
Also, my local public library has issues of Architectural Record dating back to 1960. One issue is all about the wave of the future for urban planning - Think Radiant City in Center City Philadelphia - it's great.
What's your experience with such books/magazines?
